SLING-SHOT.

Specification of Letters I'atent.

Patented Sept. 3, 1918.

' Application filed January 1a, 1918. Serial No. 212,480.

To all'whom it may concern:

Be it known that I, Anmson R. DE Pass, a citizen of the United States, and residing at Columbia, county of Richland, State of South Carollna, have invented certain new and useful Improvements in Sling-Shot, of which the following is a specification:

This invention relates to slings or catapults which are adapted to be used by boys for the purpose of throwing a missile. T propulsive force is given to the missile by the elasticity of bands which 'are usually made of rubber. In devices of this kind the point where the instrumentusually' wears out or becomes defective first, is at the point where the rubber bands are secured either to the frame or to the missile carrier. It has been my purpose to produce a construction which will not onl be more lasting and efficient than in devices of this kind known to me, but which will also have an ornamental appearance. The novel features of the invention will be'apparent from the following description taken in-connection with the drawings.

In the drawings g Figure 1 is a perspective View of the device embodying my invention;

Fig. 2 is a detail vertical section through the fastening means at the end of the prongs;

Fig. 3 is a detail cross sectional view of the fastening at the missile holder; and

Fig. 4 is an enlarged front view of a rubber band having a piece of protecting fabric secured to its end.

As shown in Fig. 1, the device embodies a main frame made up of the handle 10 and the prongs 11 and 12, together with the rubber bands 13 and 14 and the missile holder 15. The main frame may be made of any suitable material, but I prefer to make it of metal, and the bands 13 and 14 will usually be made of solid rubber. The missile holder 15 is preferably made of leather.

As shown in Fig.2, each of the prongs is provided at its top with grooves 16 and 17 and the ends of the bands 13 and 14 are placed vertically against the ends of the prongs over these grooves. In, the preferred form of my invention a protecting fabric 18- is placed on the outer surface of the rubber bands 13 and 14 and this fabric is made in the form ofadhesive tape which may be made to stick to the surface of the band. -A flexible fastening means, such as a thread 19, 1s then wound around the end of the band and the end of the prong, so as to tightly hold the band in position, the grooves 16 and 17 cooperating to this end. The interposed fabric 18 serves to prevent the threads from cutting and wearing the soft rubber of the band. After the parts are thus securely fastened, a rubber collar 20 is moved into position to entirely cover the fastening means and to a certain extent reinforce it. It prevents the fastening threads from being broken or worn and also produces quite an ornamental appearance.

The fastening at the missile holder is similar to that at the end of the prongs. The ends of the bands 13 and 14 are passed through slots 21 and 22 in the end of the holder and are folded back on the band, as shown in Fig. 3. A piece of protecting fabric 23 is wrapped around the folded ends and the thread 24 is then tightly wrapped around this fabric compressing the rubber and is tied so as to securely hold. The rubber collar 25 is then placed in position over the fastening.

Having thus described my invention what is claimed as new and desired to be secured by Letters Patent is;

1. A sling comprising a main frame including two prongs, elastic bands fitting against said prongs attheir ends, flexible fastening means Wrapped around said ends and bands to fasten said bands securely to said prongs, and protecting collars on the ends of said prongs fitting over said fastening means to reinforce and protect the same.

2. A sling comprising a main frame including two prongs, elastic bands fitting against said prongs at their ends, flexible fastening means wrapped around said ends and bands to fasten said bands securely to said prongs, and rubber collars on the ends of said prongs fitting tightly over said fastening means.

3. A sling comprising a main frame including two prongs, elastic bands fitting against said prongs at their ends, flexible fastenin means wrapped around said ends,

and ban s to fasten saidbands securely to said prongs, a protecting-fabric interposed between said band and the said fastening means to prevent said fastening from outting band, and protecting collars on the ends of said pron s fittin over said fastenv mg means to rein orce an protect the same. 4. In a device of the class described the 5 combination with a frame provided with two prongs, of two rubber bands, a missile holder and means for securing said bands at one end to said prongs and at the other end to said holder comprising tightly drawn windings of thread with protecting pieces of 1C fabric between said threads and rubber bands and rubber collars fitting over said windings.

In testimony whereof I aflix my signature. I
